The area a buyer is charged for, made up of the flat's built-up area plus a share of the building's common areas.

## What is Super Built-up Area (Saleable Area)?

Super built-up area is the area an apartment buyer is charged for. It is the [built-up area](https://superwise.site/glossary/built-up-area/) (the flat and its walls) plus a proportionate share of the building's common areas, such as lobbies, staircases, lift shafts, clubhouse and corridors. Before [RERA](https://superwise.site/glossary/real-estate-regulatory-authority/) required sale by [carpet area](https://superwise.site/glossary/carpet-area/) it was the usual measure in Indian real estate, and because it inflates the square footage, it makes the price per square foot look lower.

## Practical example

A developer advertises an apartment at ₹5,000 per sq.ft with a super built-up area of 1,500 sq.ft, a total price of ₹75,00,000. The carpet area the buyer can actually live in is only 1,000 sq.ft. The extra 500 sq.ft pays for the buyer's 5% share of the building's lobby and swimming pool.
